UHMWPE (Ultra High Molding Weight Polyethylene) extrusion molding die

The utility model discloses an UHMWPE extrusion forming die which comprises a melting section and a cooling shaping section, and the cooling shaping section is located on one side of the melting section. The melting section is used for melting and conveying an interlayer base material of a co-extrusion composite material and compounding the interlayer base material with an inner-layer nano composite material and an outer-layer nano composite material; the cooling and shaping section is used for cooling and shaping the compounded material; wherein channels are formed in the melting section and the cooling and shaping section; according to the technical key points, the UHMWPE extrusion molding die disclosed by the utility model realizes nano-composite functionalization of the inner surface layer and the outer surface layer through a co-extrusion scheme, meanwhile, the mechanical property of a base material is ensured, and the problem that the mechanical property of a polyolefin product is reduced due to nano-co
